It was in the Polish-Lithuanian Commonwealth that existed long before British Commonwealth. The Tatars who at first fought with Poles signed agreement of peaceful coexistance. The other type of Islamic group calls itself Karaim, which is interesting mixture of Islamic(Turkish) and Hebrew culture. There is Karaim’s minority in Lithuania. Unfortunately however even remnaants of Tatars from Central Europe are being radicalized by Saudi teachers. Dr Jasser is right.
